Abstract
"DISPOSITIVO GERADOR DE FORçA AERODINâMICA ATRAVéS DA CIRCULAçãO DO FLUIDO SOBRE UMA SUPERFìCIE", através um dispositivo que, pela circulação induzida do fluido a partir de um movimento de rotação de um ou mais dispositivos cilíndricos, produz uma diferença de pressão numa superfície, o que resulta numa força aerodinâmica (no caso do fluido ser o ar). Esta força aerodinâmica pode ser usada, por exemplo para sustentar corpos mais pesados do que o ar, consumindo uma potência menor do que a requerida nos dispositivos usados atualmente. Os cilindros concêntricos (1) são postos em rotação a alta velocidade por alguma força motriz. O movimento de rotação dos cilindros (1) induz nas partículas do fluido (ar) uma velocidade predominantemente azimutal. Este campo de velocidades induzido provoca uma alteração da pressão no fluido, que, atuando sobre apenas uma das faces de uma superfície (2), gera uma força aerodinâmica sobre a dita superfície. Esta superfície pode ser parte de um veículo ou estar acoplada ao mesmo. Uma outra forma de se gerar uma força aerodinâmica a partir da circulação do fluido induzida é através de uma hélice (5) imersa no dito fluido, sendo que esta hélice pode estar estacionária ou se movendo no sentido contrário ao do cilindro (1). A velocidade relativa entre o fluido e a hélice (5) provoca na superfície da hélice uma força aerodinâmica. No caso de a hélice estar estática, tal dispositivo apresenta vantagens sobre os atuais, uma vez que simplifica os mecanismos de controle de passo da hélice. No caso de a hélice em rotação no sentido contrário ao do cilindro (1), um ganho de eficiência pode ser observado em relação aos atuais dispositivos, uma vez que a velocidade relativa entre o fluido e as pás da hélice pode alcançar valores bem mais elevados."AERODYNAMIC FORCE GENERATOR DEVICE THROUGH THE FLUID CIRCULATION ON A SURFACE", through a device that, by the induced circulation of the fluid from a rotation movement of one or more cylindrical devices, produces a pressure difference on a surface, which results in an aerodynamic force (in case the fluid is air). This aerodynamic force can be used, for example to support bodies heavier than air, consuming less power than is required in devices currently used. The concentric cylinders (1) are rotated at high speed by some driving force. The rotation movement of the cylinders (1) induces a predominantly azimuth velocity in the fluid (air) particles. This induced velocity field causes a change in the pressure in the fluid, which, acting on only one face of a surface (2), generates an aerodynamic force on said surface. This surface can be part of a vehicle or be attached to it. Another way to generate an aerodynamic force from the induced fluid circulation is through a propeller (5) immersed in said fluid, this propeller can be stationary or moving in the opposite direction to the cylinder (1). The relative speed between the fluid and the propeller (5) causes an aerodynamic force on the surface of the propeller. In case the propeller is static, this device has advantages over the current ones, since it simplifies the propeller pitch control mechanisms. In the case of the propeller rotating in the opposite direction to the cylinder (1), an efficiency gain can be observed in relation to the current devices, since the relative speed between the fluid and the propeller blades can reach much higher values .
